IMPROVEMENT iN OPEN LINKS FOR COUPLING D'UBLE ANDSWHIFFLETREES.

The Schedule referred to in these Letters Patent and making part of the same.

1 LNnwfroNG. SAMPLE, of Penningtonville, in the county of 'Chester and State ofPennsylvanimhave invented an .Improved Open Link for Coupling, of which the following is a specification.

The object of my invention is to provide an openlink for coupling the single-tree tothe double-tree without the sharp or tapei'ed overlappingends, as in the common open-link in use, so apt to injnre horses when backing up againsttheni, as experience has proved those links not only dangerous, but apt, also,

to, with its pointed ends. This improved open-link A, .of the desired size and strength, has a foot, a, on each end, projecting on both sides, with space sucient between them to` inscrtanother link or igen loop, or frigen 0,' ,fas shown on the end of the double-'tree B, and C', centrally,on the single-tree E.

These blunted and projecting feetor cross-ends (te, will prevent the uncoupling by any-chance position?.-

or movement of the connected paits, butl by hand the coupling and uncoupliug are-readily performed.

Simple and useful asI this open-.link is, I ani-not aware that it hasr ever been used. I am aware, however,that patent No. 19,955,'Apri1 13, 185,8, claims a shackle oy'cl1ainlink,.made in two parts, and with one ofthe'm formed in one piece as a double hook, and space between the cxtremities,with tenons for the-"other piece-telit in and lap over the hooks; such a link or shackle I do not claim.

' What I claim as my invention, and desire .to secnre by Letters Patent, isfL An open-link, A, with itsextremities a turned ont on both sides, in the manner`- shown and for the purpose specified.
